I have the necessary skills to work on your project, but do not speak it fluently read and understand English very well.
I can work from 4 to 6 hours a day.
I pass a query to you to look, that query given the point that you had takes the values less than 100mts :
SELECT
id, (
6371 * acos (
cos ( radians(27.721791666666665) )
* cos( radians( latitude ) )
* cos( radians( longitude) - radians(85.32254833333333) )
+ sin ( radians(27.721791666666665) )
* sin( radians( latitude ) )
)
) AS distance
FROM positions
HAVING distance < 0.10
ORDER BY distance
Check it.
